Abstract(s)
During the ageing process of wine spirits several phenomena occur, which are
responsible for the final quality of the beverage.
This work aimed to discriminate the aged wine spirits according to the wood species,
ageing technology and ageing time using FT-Raman methodology. For this purpose,
the same Lourinhã wine distillate aged in 250-L wooden barrels of Limousin oak
wood (L) and chestnut wood (C) separately and used together (L + C), was monitored
through FT-Raman during the first 12 months of ageing. This technique was also
applied to the same wine distillate aged in stainless steel tanks with staves of the same
kinds of wood and during the same period.
FT-Raman allows separating the wine spirits according to the different wood species
and ageing time. This technique seems to be a promising tool to monitor the ageing
process of wine spirit through different technologies.
